When I first watched this short video I had no idea of what was going to happen in it. I did, however, immediately note at the start of it the Pet Shelter Guy was holding the cat in a bad way. It only took about 15 seconds for things to go south.
I swear I truly laughed hard and long. The second time I watched the video it was even funnier. Brought tears to my eyes. If you don't understand cats and worse don't know THE cat you are confronted with, walk away. Just walk away.
